infill walls under IP-OOP loading. With a reduced scale of 1/2, the frame is an RC frame with a single-layer, single-span, non-hollow infill wall. Fig. 7 shows the dimensions and rebar arrangement of the frame. Tab. 8 lists the material properties.

Figure 8: Simulated and test hysteresis curves.

According to the test information, the mechanical parameters of the infill wall were calculated. After loading, the model was subjected to IP-OOP loading. Fig. 8 compares the simulated hysteresis curve with the test data. Fig. 9 compares the simulated and test backbone curves. The simulation results basically agree with the test results.
